基于非线性动力系统理论的土木工程安全性判断

本文将土木工程监测对象视为一个受多种因素共同影响的动力系统,根据非线性科学相关理论,利用实际的监测数据通过相空间重构的方法来重建该系统,并根据Renyi熵来了解其运动演化规律,从而对监测对象的安全性做出判断,是土木工程变形监测数据分析的一种新方法。文中以某水电站引水发电系统隧道变形监测的实测数据为例,给出了计算分析结果。

Estimation of Civil Engineering Safety by Analyzing Monitoring Data Based on Theory of Non-linear Dynamic System

The monitored civil engineering structures were considered as a dynamic system influenced by various factors, the system was reconstructed by phase space reconstruction and the entropy was employed to evaluate the safety of monitored structures. An example was given to demonstrate the novel method of data processing in deformation measurement.
